Chaluhe Basin is in Jilin
Province of China with a cumulative sedimentary rock thickness of about 6000
meters and has four subdivisions: Wanchang Structural High, Bo-Tai Sag, Xinanpu
Sag, Liangjia Structure High and the Gudian Slope. The basin with its better
source rock distribution and more favorable maturation indicators than the
adjacent Moliqing and Luxiang Basins is expected to be a potential hydrocarbon-producing
basin. Four (4) wells were used in determining the maturation hydrocarbon
generating potential of the mudstone beds present in the Eocene Formations
(Shuangyang, Sheling and Yongji). Obtained result revealed heat flow average of
71.8 mW/m2, oil generation between 3.15 mg/g TOC and 39.49 mg/g TOC
with gas generation of 6.98 mg/g TOC to 92.83 mg/g TOC. In conclusion the
Eocene Shuangyang mudstone is the main petroleum source rock.
